In the mid/late 90's Robinair made a a refrigerant gauge with wired pressure transducers, but they had severe issues with transducers failing. I went through 6 or 7 transducers in 2 months before United just started giving people their money back on it. Was >$500 for the setup 15ish years ago.

I have a wireless tool with no hoses I use to check pressures. Whentn got me a tire pressure Gage. Just pop it on the suckin line and when it's under 60 just add some freezon. Whal it's just like a tyre.
